Problems solved by technology

As a key component of sewing equipment, the rotary hook has high requirements for manufacturing and high production costs. In addition, the rotary hook is easily damaged during use and has a high failure rate, resulting in a relatively short service life.
When sewing, when the hook is running at high speed, it is necessary to add grease to the hook body and the high-speed rotating part of the shaft. In addition, the high-speed rotating hook needs to be supported by the mechanical transmission system of the sewing machine, which needs to be matched with a complex gear set , which increases the cost of the sewing machine
The rotary hook and its rotating shaft need to be lubricated, causing pollution to the sewing thread and fabric, and reducing the sewing quality; the high-speed operation of the rotary hook restricts the development of intelligent automation, oil-free, and lightweight sewing equipment

Embodiment 1

[0025] combine figure 1 figure 2 image 3 and Figure 4 A kind of suspending rotary hook for hooking thread of the present application has motor 91 , rotary hook fixing seat 3 , suspended bobbin 7 , machine needle 2 , positioning connecting rod 92 , thread stand 6 and hook needle 5 . The rotary hook fixed seat 3 of the present application is a fixed type, that is, the rotary hook fixed seat 3 is connected to the positioning connecting rod 92, and the rotary hook fixed seat 3 and its positioning connecting rod 92 are stationary during the sewing process, and the positioning connecting rod 92 Indirectly or directly fixed on the base plate (or base) of the sewing machine head 1, the machine needle 2 has a hooking place 21 for the hooking needle 5 to hook the thread.

[0026] Above-mentioned motor 91 has hollow main shaft 911, and hollow main shaft 911 is motor output shaft, and positioning connecting rod 92 passes hollow main shaft 911, and bearing 93 is arranged between holl...

Embodiment 2

[0039] exist Figure 8 and Figure 9 Among them, this second embodiment is basically the same as the above-mentioned first embodiment, the difference is that the machine needle 2 of the first embodiment is perpendicular to the thread frame 6, and also has a needle plate 8, and the front end of the above-mentioned machine needle 2 is on the needle plate 8 The needle plate hole 81 on the top operates, the machine needle 2 is perpendicular to the needle plate 8, the needle plate 8 is above the hook needle 5 and the suspension bobbin 7, and the hook needle 5 is on the tangent plane of the hook line 21. The machine needle 2 passes through the needle plate 8 with the upper thread 1a and enters the initial hooking state. The needle tip of the above machine needle 2 runs in the needle plate 8, and the machine needle 2 works under the needle plate 8 on the outside of the suspended bobbin core 7. The hook needle 5 and the suspension bobbin 7 and the suspension bobbin 7 are non-contact ...

Abstract

The invention provides a thread hooking suspension rotating shuttle, and particularly relates to the technical field of sewing machine manufacturing. Comprising a rotating shuttle fixing seat and a suspended shuttle peg, a positioning device is arranged between the suspended shuttle peg and the rotating shuttle fixing seat, preferably, a positioning convex block of the suspended shuttle peg is arranged on one side close to the rotating shuttle fixing seat, the rotating shuttle fixing seat is further provided with a positioning groove, and the positioning convex block of the suspended shuttle peg is positioned in the positioning groove of the rotating shuttle fixing seat. The thread hooking suspension rotating shuttle has the advantages that lubricating oil is not needed, contact and abrasion are avoided, the service life is long, a complex change gear set does not need to be matched, the performance of the whole sewing machine is improved, the manufacturing cost of the sewing machine is reduced, and the thread hooking suspension rotating shuttle has the advantages that the design and manufacturing thinking of a traditional sewing machine is subverted; and the popularization value is high.

Description

technical field [0001] The application proposes a thread-hooking suspension hook. The hook-line suspension hook of this program is applied to household sewing machines, industrial lockstitch sewing machines, thick material machines, embroidery machines, roller carts and other sewing equipment that use the hook. Sewing machine manufacturing technology field. Background technique [0002] As a sewing machine for cloth, the sewing machine has a history of more than two hundred years of development. It has made a significant contribution to the development of the clothing industry in human society and promoted the development of human civilization. Throughout the history of the development of sewing machine technology, the rotary hook still follows the original scheme, and the technical principles implemented remain the same. As a key component of sewing equipment, the rotary hook has high requirements for production and manufacturing, and the production cost is also high. In a...
